Hi Kevin,

My friend's manifold is around three years old. Never polished and it remains very shiney with no discoloration. He also changed his valve covers to chrome and reduced the amount of chrome fittings and braided hose and a K&N air cleaner that has an element built in the top. He also has an Edelbrock Durashine carburator. Much better look than before, more tastful. To me chrome and aluminum don't mix very well, it's one or the other.
